How 3D printing will change the world. Johannesburg-based company DemaPlasTech says 3D printing is going mainstream and will change manufacturing forever. By Duncan McLeod. An adjustable spanner created on an Objet 3D printer In a nondescript office park northwest of Fourways in Johannesburg, a printer was whirring away. But this was no ordinary printer. The Connex model from Israeli firm Objet Geometries is a 3D printer that jets a range of materials simultaneously to create 3D models.
When TechCentral visited local Objet distributor DemaPlasTech, the R2,2m printer was humming away industriously, building a fully functional fitting for a garden tap (see video below). If the proponents of the technology are right, 3D printing could herald a revolution in the way the world makes things. The Economist , in an April cover story, suggested that 3D printing, also sometimes referred to as additive manufacturing, would lead to the digitisation of manufacturing and bring about the third industrial revolution.

A precondition of a good working simple motion detection is that you can disable the autofocus on your camera and that you have a good control over the lightning situation (so no sun/cloud change or large shadows).
The first step to determine the position of a moving item in the field of view of your camera is to compare frames to each other. In a stream of video you can either compare the previous to the current frame or a previously selected frame to the current one. The fist method will give us the movement, but we will lose the coordinates when the movement is very small or stops. [pix_movement] Compare the previous frame to the current one. This will result in all pixel information blacked out exept the space where a difference is detected relative to the previous frame. [pix_background] It is the cousin of pix_movement with the difference that we can set the reference frame to which the current frame is compared.
[pix_blob] either way, we need another object: [pix_blob]. Theoretically Correct: Chord Finder, Song Transposer, Chord Transposer, Free Online Music Theory and Music Lessons.
